How to handle Artist and Albumartist

[Ooteboe]

Can someone please tell me how to place the following tags:

Oistrakh, David [Violin]
London Symphony Orchestra
Matačić, Lovro von [Conductor]

I want to see this nicely grouped together when opening up the metadata (BubbleUPnP) AND I want them in the index-tags, to be able to browse on them.

When I put the tag 'Artist' in itemtag as well as in indextag (Options Minimserver), I get a conflict. And I not succeeded to get the information from 'Albumartist' into the metadata (BubbleUPnP).

Thanks,
